How to lower kh without lowering ph?

[Gigaboom]

I just put 2 clownfish and 2 astrea snails in my first tank (10gal) yesterday, and today I did a water test. the ph was low, so I tried to increase it to acceptable levels using baking soda. I then noticed that my tank now was at 25 dkh. How do I lower the kh quickly without lowering the ph?

Do a series of small water changes of several days, and stop mucking with the tank. Don't aim to change anything quickly and don't chase numbers, just aim for stability.

like 10% once a day?

15-20% daily for 4 to 5 days.
